The development of power devices has increased the density in electronics systems. With regard to the ranking, the density is described as the quantity of power that can be comfortably housed within a specific volume or space. A higher density assists in allowing electronic systems which are more compact, lightweight, and suitable for applications with limited space constraints. Enhanced density is an outstanding attribute not only in terms of space conservation but also for the excellent system integration and reduction in overall system costs.
